Come To Friday's early morning class (6:10am) to see this one in action! I'm calling it a "band plank with row". You may decide to call it "really hard", or maybe you have another name for it! Here's the deal: You get into a plank position. Some of you may stop there--it's hard enough! On your forearms (use extra cushioning if you need to) and your toes. In front of you, you've attached a band to something solid, just at about mid calf level, although a bit higher will work. Now while maintaining that plank position, you pull the band back on one side. Do 12, then repeat on the other side. Rest, and do 2 more sets of 12 per side.
